How the Mounjaro Dose Schedule Generally Works
Mounjaro is a once-weekly injectable medicine whose active substance, tirzepatide, acts on both GLP-1 and GIP receptors — pathways involved in appetite regulation and blood sugar management. According to information published on the electronic Medicines Compendium, tirzepatide is typically introduced at a low dose and increased gradually over time, with each stage lasting several weeks before any adjustment is considered.
The dose stages in context
The commonly referenced dose strengths for Mounjaro are 2.5mg, 5mg, 7.5mg, 10mg, 12.5mg, and 15mg. In a standard schedule:
- 2.5mg is the usual starting dose, allowing the body to adjust to the medicine before any increase.
- 5mg follows after several weeks at 2.5mg, again if your prescriber decides it is appropriate.
- 7.5mg and beyond may follow in further steps, each guided by your prescriber and your individual response.
It is worth noting that not everyone will progress through every stage, and some people remain on a dose lower than the maximum. The right dose for you is determined by your prescriber, taking into account your full medical history and how you are tolerating the medicine.
Side effects and the titration process
Gastrointestinal side effects — such as nausea, indigestion, or changes in bowel habits — are commonly reported, particularly in the days following a dose increase. For many people, these settle as the body adjusts to the new dose level. If you find side effects are notable at 5mg, that is worth discussing with your prescriber rather than making any changes independently.
You can find further factual information about tirzepatide in the electronic Medicines Compendium (eMC), where the full patient information and prescribing details are published. Any side effects should be reported to your healthcare professional and to your national reporting scheme (such as the UK's Yellow Card scheme or the equivalent in your country).

Tracking Your Mounjaro Doses with GLP Trackr
One of the most practical things you can do at any dose stage is keep an accurate log of every injection — and that is exactly where GLP Trackr starts. The app's dose logging feature lets you record each weekly shot: the dose strength (so you always know whether you are on 2.5mg, 5mg, 7.5mg, or another stage), the date, and the time. Over weeks, this builds a clear, date-stamped record you can bring to your next prescriber appointment.
Beyond the shot itself, GLP Trackr also lets you log side effects as they happen, so patterns become visible over time. If nausea or fatigue is more noticeable in the day or two after your 5mg dose, logging it consistently means you have real data to discuss — rather than trying to recall details at a later appointment. The app can generate a summary report to support exactly those conversations.
Dose reminders are also built in, so a weekly injection is never accidentally missed. If a dose is missed, the right course of action is always to contact your prescriber or check your patient information leaflet — the app can log the gap so it is visible in your record.
Always follow the guidance of your prescriber or doctor regarding your dose — they know your full history and are best placed to advise on any adjustments. GLP Trackr records your journey; it does not replace clinical advice.
For a broader overview of managing your Mounjaro treatment, the Mounjaro 5mg guide covers this dose stage in depth. You may also find the pages on finding value on 5mg Mounjaro and how 5mg Mounjaro is obtained useful reading.

Frequently asked questions.
The 5mg dose of Mounjaro (tirzepatide) is the second step in a prescriber-led titration schedule, typically reached after several weeks on the 2.5mg starting dose. Whether and when to progress to 5mg is always a decision made by your prescriber.
Dose decisions for Mounjaro are made by your prescriber based on your individual response, tolerability, and medical history. The schedule generally starts at 2.5mg and may increase gradually through 5mg, 7.5mg, and higher stages — but progression is not automatic and varies by person.
If you miss a dose, check your patient information leaflet and contact your prescriber or doctor for guidance — never double up or adjust your schedule independently. GLP Trackr can log a missed dose so the gap is visible in your record when you speak to your healthcare professional.
Nausea and other gastrointestinal effects are commonly reported around dose increases, including the move to 5mg. For many people these ease as the body adjusts. If symptoms are severe, persistent, or worrying, contact your healthcare professional promptly rather than managing them alone.
GLP Trackr lets you log each weekly injection — recording the dose strength, date, and time — and sends reminders so you never miss a shot. You can also log side effects alongside your doses, building a record to discuss with your prescriber at appointments.
